Kyselo (; ) is a soup based on
rye sourdough and
mushrooms. It is a traditional
Czech cuisine from poor folk food originating in the Northern
Bohemia highland region of the
Giant Mountains. It is made from locally accessible, cheap, storable ingredients (the mushrooms are usually used dried) and nutritious ingredients so it provides substantial energy for hard mountain life and work. Historically kyselo was made without eggs. Eggs in early times were produced mainly for sale on the market, not for one's own family, so eggs were only eaten on some holidays. Potatoes became widespread among poor people of
Czech lands in the late 18th century, so before that time soups of this type were also made without potatoes.
Etymology The word
kyselo is
derived from the Slavic word (Polish, Slovak, Czech) "kisić" "to make sour",
kyselý, which means 'sour' in
Czech. The sourdough which kyselo is made from is called "chlebový kvásek" or "chlebový kvas" (not to be confused with the Russian
kvass). Sometimes another sour mushroom-based Czech soup
kulajda or its variants are mistakenly called
kyselo. The difference is that
kulajda and similar soups do not use sourdough but
sour cream or milk and vinegar. To reduce this misunderstanding, kyselo is often called
Krkonošské kyselo ("Giant Mountain Kyselo"). In Eastern regions of the Czech Republic and in
Slovakia there is a soup called
kyselica, but it is a variation of
sauerkraut soup.
Ingredients and preparation The basis of kyselo is strong
broth made from mushrooms and
caraway in water. Central European
mushroom species such as
cep and similar ones are used. The mushrooms are usually used dried in the winter. Due to its ancient origins, kyselo has no fixed recipe, and the preparation is a little different in every family. The recipe is passed on by
oral tradition. There are local variants of kyselo in the Giant Mountains: without eggs or with
hard-boiled eggs, boiled but not roasted potatoes, with or without cream, etc.
Instant powder kyselo base is now available for use in large catering kitchens or liquid fermented cereal.
Serving Kyselo is sometimes served in an edible
bread bowl. In the Giant Mountains there is also a peak called the
Kotel (, ) which means
cauldron. When fog rises from the valley at bottom of Kotel, people say that Krakonoš is cooking the kyselo. The name
kyselo is well-known throughout the Czech Republic because of
Večerníček children's television series Krkonošské pohádky (
Fairy Tales from the Giant Mountains), in which Anče, one of the main characters, cooks
kyselo in almost all of the episodes. == Similar dishes ==
